I Thessalonians 5:6-8

6 So then, let us not be like others, who are asleep, but let us be alert and self-controlled.

7 For those who sleep, sleep at night, and those who get drunk, get drunk at night.

8 But since we belong to the day, let us be self-controlled, putting on faith and love as a breastplate, and the hope of salvation as a helmet.
